Installing libpng version 1.0.3 - January 14, 1999
|
|
|
|
Before installing libpng, you must first install zlib. zlib
|
|
can usually be found wherever you got libpng. zlib can be
|
|
placed in another directory, at the same level as libpng.
|
|
Note that your system might already have a preinstalled
|
|
zlib, but you will still need to have access to the
|
|
zlib.h and zconf.h include files that correspond to the
|
|
version of zlib that's installed.
|
|
|
|
You can rename the directories that you downloaded (they
|
|
might be called "libpng-1.0.3" or "lpng103" and "zlib-1.1.3"
|
|
or "zlib113") so that you have directories called "zlib" and "libpng".
|
|
|
|
Your directory structure should look like this:
|
|
|
|
.. (the parent directory)
|
|
libpng (this directory)
|
|
INSTALL (this file)
|
|
README
|
|
*.h
|
|
*.c
|
|
scripts
|
|
makefile.*
|
|
pngtest.png
|
|
etc.
|
|
zlib
|
|
README
|
|
*.h
|
|
*.c
|
|
contrib
|
|
etc.
|
|
|
|
First enter the zlib directory and follow the instructions
|
|
in zlib/README. Then come back here and choose the
|
|
appropriate makefile.sys in the scripts directory.
|
|
The files that are presently available in the scripts directory
|
|
include
|
|
|
|
descrip.mms => VMS makefile for MMS or MMK
|
|
makefile.std => Generic UNIX makefile
|
|
makefile.knr => Archaic UNIX Makefile that converts files with ansi2knr
|
|
makefile.dec => DEC Alpha UNIX makefile
|
|
makefile.hux => HPUX (10.20 and 11.00) makefile
|
|
makefile.sgi => Silicon Graphics IRIX makefile
|
|
makefile.sun => Sun makefile
|
|
makefile.s2x => Solaris 2.X makefile (gcc, creates libpng.so.2.1.0)
|
|
makefile.lnx => Linux/ELF makefile (gcc, creates libpng.so.2.1.0)
|
|
makefile.mip => MIPS makefile
|
|
makefile.aco => Acorn makefile
|
|
makefile.ama => Amiga makefile
|
|
smakefile.ppc => AMIGA smakefile for SAS C V6.58/7.00 PPC compiler
|
|
(Requires SCOPTIONS, copied from scripts/SCOPTIONS.ppc)
|
|
makefile.atr => Atari makefile
|
|
makefile.bor => Borland makefile
|
|
build.bat => MS-DOS batch file for Borland compiler
|
|
makefile.dj2 => DJGPP 2 makefile
|
|
makefile.msc => Microsoft C makefile
|
|
makefile.w32 => makefile for Microsoft Visual C++ 4.0 and later
|
|
makefile.tc3 => Turbo C 3.0 makefile
|
|
makefile.os2 => OS/2 Makefile (gcc and emx, requires pngos2.def)
|
|
pngos2.def => OS/2 module definition file used by makefile.os2
|
|
makefile.wat => Watcom 10a+ Makefile, 32-bit flat memory model
|
|
makevms.com => VMS build script
|
|
pngdll.mak => To make a png32bd.dll with Borland C++ 4.5
|
|
pngdef.pas => Defines for a png32bd.dll with Borland C++ 4.5
|
|
|
|
Copy the file (or files) that you need from the
|
|
scripts directory into this directory, for example
|
|
|
|
MSDOS example: copy scripts\makefile.msd makefile
|
|
UNIX example: cp scripts/makefile.std makefile
|
|
|
|
Read the makefile to see if you need to change any source or
|
|
target directories to match your preferences.
|
|
|
|
Then read pngconf.h to see if you want to make any configuration
|
|
changes.
|
|
|
|
Then just run "make test" which will create the libpng library in
|
|
this directory and run a quick test that reads the "pngtest.png"
|
|
file and writes a "pngout.png" file that should be identical to it.
|
|
|
|
Most of the makefiles will allow you to run "make install" to
|
|
put the library in its final resting place (if you want to
|
|
do that, run "make install" in the zlib directory first if necessary).
|
|
|
|
Further information can be found in the README and libpng.txt
|
|
files, in the individual makefiles, and in png.h, and the manual
|
|
pages libpng.3 and png.5.
